SUMTEQ - History

SUMTEQ is a high-tech start-up which was founded in 2014 in Cologne. SUMTEQ’s target is to produce and to market SUMFOAM, an innovative nanoporous high performance material.

Alexander Müller and Roland Oberhoffer, two of its managing partners, made up their mind to continue their work on the development of SUMFOAM after they had finished their studies in chemistry with a PhD at the University of Cologne instead of leaving their know-how behind in dusted bookshelves. Having done a lot of profound research with promising results, Alexander and Roland were convinced of being able to improve insulation materials with SUMFOAM. They both were much supported by their doctoral advisor Professor Strey, who is also a co-founder of SUMTEQ. Michael Hoffmann was involved in the company right from the start and he complements the company’s founding team with his expertise in finance, strategy and organization development, having acquired his professional business experience in years before.

The SUMTEQ-team is a composition of complementary, target-oriented, conscientious persons who can also think unconventionally and sometimes are spontaneous when creative ideas come up. For them problems mean challenges and their first priority is to find solutions for their customers’ needs.
